The first shows groups of calculations involving addition, subtraction and multiplication where the answers can be revealed. The second interactive sheet is similar, but it deals with calculations involving division instead of multiplication. The next sheet deals with calculations with the four operations and brackets whilst the final sheet requires students to insert brackets to make the shown calculations correct. The final sheet requires teacher input as students are asked to say if any of the brackets in the answers are unnecessary.
